Oracle DOA/Application connection problem.

I am looking for some help with a problem we are having with a connection issue with DOA objects and Application objects. We have a number of programs that were written using Delphi (version 5) that contain DOA (Direct Oracle Access) objects and Application Objects. The problem seems to be the order in which the connections are made. We have created a test program that proves this for us.
Our environment is a Windows 2003 Server Standard x64 Edition SP2 with Oracle 10.2.0.3 installed. The processor is a dual core processor with 4 gbs of ram.
When we open Delphi, load the program connect the application (using the application object) and then connect with the DOA object there is no problem. There is 2 connections and the program runs fine.
Whenwe open Delphi, load the program, connect the DOA object and then connect the application object the server hangs. the hour glass displays and sits there. The memory associated with the oracle.exe process continues to get larger and larger (looking in task manager) then when it reaches 1, 386, 750KB approximately the Oracle database service ceases and the windows creats a dump file (oracle.exe.hdmp) the size of the memory allocated. The following trace file is created:
Dump file e:\oracle\product\10.2.0\admin\alt2prod\bdump\alt2prod_lgwr_2448.trc

It appears the connection is trying to connect a second time. Does anyone know how to resolve this issue. Is there a configuration parameter to resolve this issue so the server does not lock up and then crash the database service.
Any help would be appreciated.

Did you install the Oracle Lite runtime on your WM5 device properly? What CAB file did you use? It seem like you didn't install the runtime on your device at all....

How to solve Oracle SQL Developer connection problem ?

Folks,
Hello. I am using Oracle Database 11gR1. The Database Control Console https://localhost.localdomain:1158/em works correctly. I can create a Database and a table successfully.
My OS is Linux and connects to internet successfully.
In order to run SQL statements. we need to use Oracle SQL Developer. I connect Oracle SQL Developer in the following way:
Connection Name: DB1 (this is my database name as well)
Username: SYS (this is the user name I used to login to the Console)
Password: SYS (this the password used to login to the Console)
Connection Type: Basic
Host Name: localhost
Port: 1158
SID: DB1 (this is created during installing the Database)
But the error message comes up: "Status: Failure - IO exception Connection Reset."
Can any folk tell me how to solve Oracle SQL Developer connection problem ?

password: enter_your_correct_password given at the time of oracle installation
role: select sysdba if you would connect as sysdba else select normal for users other than sys
hostname: enter your oracle server hostname or ip address eg:- 192.168.11.12
to find the hostname open terminal/command prompt in oracle installed machine
type ---> hostname
type ---->ping hostname
you can find the ipaddress of the server
port number: 1521 (default) ----> i guess , else check the port number in the tnsnames.ora file under your ORACLE_HOME/network/admin folder
SID: DB1
try it

..... PHP oracle.. application connectivity issue.......

all.
We have oracle 9i release 2 databse installed and acced by clients using Forms 6i.
Due to some reasons we are shifting to Oracle 10g rel 1 and PHP as front end.
The new server machine has windows 2000 professional with service pack 4.
i installed orcl 10g rel1 on it. I configured the PHP and place the application pages on the folder and it is workign fine.
Now the problem is that when i try to access the application from my computer it shows me the error as
"Database connection error." This error is hardcodded by me , if there is any issue in connectivity , i have hardcoded that my user will see this error.
a few of the clients when they type the machine name on thier browsers see this error
" PHP Warning: Unknown(): Unable to load dynamic library './extensions/php_oci8.dll' - Access is denied. in Unknown on line 0 PHP Warning: Unknown(): Unable to load dynamic library './extensions/php_oracle.dll' - Access is denied. in Unknown on line 0 "
My database clients werent also connecting but the following action has caused the fault to be corrected.
wat i did was that i replace the
host=(endsys.eapa.com)
to host= (ip address).
But still i am unable to connect to the application via my webbrowser.
I have installed PHP correctly, IIS correctly,
may b there is anything to do with the permissions.
Kindly suggest something so that i may able to bring up the application
Regards

Hi: Im running IIS on a Windows Server 2000, PHP Version 4.4.2 and I have installed on the same server my Oracle 9 DB.
I have edited php.ini like:
extension_dir = "C:\PHP4\extensions"
extension=php_oci8.dll
I have run dependency walker in order to ensure all dependencys are ok.
I have granted full access to Everybody to the PHP directory
But im having the following error:
PHP Warning: Unknown(): Unable to load dynamic library 'C:\PHP4\extensions\php_oci8.dll' - Access is denied. in Unknown on line 0
Does anybody know where i should start troubleshooting this?
Thanks, Lautaro Dolberg

Oracle 11g XE Connectivity Problems

Hi to all and thanks for the attention !
Quick facts
OS : Microsoft Server 2008 R2 (x64)
Oracle Version : 11g XE (x32)
Database name : XE
I've been fighting over with providers for a whole day and I can't seem to make this work out,
I have an application(Web, on a IIS 7) that connects to a schema, the connection uses a Oracle Provider For OleDB, well at first I was getting a "Provider not registered" error, that was easy I only had to make the app run on x32 and puf the error changed, so I quickly set up the Data Source ( with the data source manager located in WOW64 ) with a oracle ole db provider, no problems, I can click on it, it will ask me for a user/password and when I click test connection I works just like I would expect it to work, now back to the application, when i set the connection string up, I get a error from the app : ORA-12154 TNS:could not resolve the connect identifier specified. So went up and tried making a udl ( invoking again the x32 ), same error ORA-12154 so I started digging and so far so good what I got is, "try tnsping <instance_Name>", did it, and got an OK (40ms) (though I had to navigate to bin folder, which was not explained in the posts, perhaps this means something ?) and also registered the oraoledb11.dll with regsvr32
Oh ! And I can connect to the database with sqldeveloper
I know really little of Oracle, any thoughts ?
Thanks again !

ORA-12154 ALWAYS only occurs on SQL Client & no SQL*Net packets ever leave client system
ORA-12154 NEVER involves the listener, the database itself or anything on the DB Server.
ORA-12154 occurs when client requests a connection to some DB server system using some connection string.
TNS-03505 is thrown by tnsping & is same error as ORA-12154 thrown by sqlplus or others.
The lookup operation fails because the name provided can NOT be resolved to any remote DB.
The analogous operation would be when you wanted to call somebody, but could not find their name in any phonebook.
The most frequent cause for the ORA-12154 error is when the connection alias can not be found in tnsnames.ora.
The lookup operation of the alias can be impacted by the contents of the sqlnet.ora file; specifically DOMAIN entry.
So post the content of the sqlnet.ora file.

Toady i have installed oracle forms 10g and oracle 10g db when i run my form it gives me this error how can i resolve it
"ora-12154 tns could not resolve the connect identifier specified"
Here are the values in forms 10g tns

What changes should i make to overcome this problem.

"ora-12154 tns could not resolve the connect identifier specified"The problem is local to the Forms Home, probably in tnsnames.ora (seems that there are tabs in IMS entry name). Carefully check it.$ oerr ora 12154
12154, 00000, "TNS:could not resolve the connect identifier specified"
// *Cause: A connection to a database or other service was requested using
// a connect identifier, and the connect identifier specified could not
// be resolved into a connect descriptor using one of the naming methods
// configured. For example, if the type of connect identifier used was a
// net service name then the net service name could not be found in a
// naming method repository, or the repository could not be
// located or reached.
// *Action:
//   - If you are using local naming (TNSNAMES.ORA file):
//      - Make sure that "TNSNAMES" is listed as one of the values of the
//        NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA)
//      - Verify that a TNSNAMES.ORA file exists and is in the proper
//        directory and is accessible.
//      - Check that the net service name used as the connect identifier
//        exists in the TNSNAMES.ORA file.
//      - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
//        file. Look for unmatched parentheses or stray characters. Errors
//        in a TNSNAMES.ORA file may make it unusable.
//   - If you are using directory naming:
//      - Verify that "LDAP" is listed as one of the values of the
//        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA).
//      - Verify that the LDAP directory server is up and that it is
//        accessible.
//      - Verify that the net service name or database name used as the
//        connect identifier is configured in the directory.
//      - Verify that the default context being used is correct by
//        specifying a fully qualified net service name or a full LDAP DN
//        as the connect identifier
//   - If you are using easy connect naming:
//      - Verify that "EZCONNECT" is listed as one of the values of the
//        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA).
//      - Make sure the host, port and service name specified
//        are correct.
//      - Try enclosing the connect identifier in quote marks.
//   See the Oracle Net Services Administrators Guide or the Oracle
//   operating system specific guide for more information on naming.

Oracle/ SQL Developer connection problem.

I have installed Oracle 11 g and SQL Developer, When I open SQL Developer and try to make a new connection ( I name the connection, put a user name in, put my password in), I click on "Test" and I get this error:
Status: Failure - Test failed: Listener refused the connection with the followong error:ORA-12505, TNS: listener does not currently know of SID given in connect descriptor The connection descroptor used by the client was:localhost:1521:ex
Can anyone explain this to me and help me resolve this issue I am having?
Thank you in advance for your help

p.s. I have also tried the user name: Scott and Password: Tiger

Windows 7 Home ... will have challenges at some point, as Oracle may not be completely compatible with Windows 7.
Aside from that, you may find firewall issues even if you are on the same machine, since the default connection from SQLDeveloper is to use the network (even loopback).
First step is to verify that the database and listener are running and that the database is registered to the listener. TO do that, drop into command line and issue:

XE =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = FCC003L)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
)and you will note the XE on the left side of the equal sign (which is a network alias), and one XE in the (SERVICE_NAME = XE) line. On YOUR system, the XE should be replaced by whatever you called your database (often 'orcl'). REMEMBER THIS ALIAS;-) and also make note of the host that your entry uses. If your host name changes because of DHCP, you're hooped (for a while).
If the database is registered (shows up in the list), the next step is to make sure a userid is available. You could use 'system' (try to avoid using SYS since it is the master userid and if you mess that up, you mess up all your homework. In a production encvironment, every access to SYS will be audited.
So, let's create a userid called me with (in 11g case sensitive) password 'myself'. Make sure that user is allow to log in (create session) and create a table.

Disconnected from Oracle Database 10g Express Edition Release 10.2.0.1.0 - ProductionIf the above worked, you should have no problem accessing the system using SQLDeveloper. You simply use the HOST, the PORT and the SID (alias) or service from the "lsnrctl status" output in the SQLDeveloper fields.
If it did not work, try dropping the "@XE" to see whether you can get in (using the bequeath connection) which is useful for troubleshooting but will not help with the traditional SQLDeveloper connection. If you get in without the @XE (or whatever your alias is) but not with it, most likely either your listener is not up or your firewall is blocking the access to the listener.

JDeveloper - Oracle 8i Lite Connection Problem

I am trying to connect to Oracle 8i Lite database on my local machine (NT as the OS) from JDeveloper 3.1.1.2, I am getting "Network adapter could not establish connection" error. I can not even do Net8 Easy Config as I have no idea what the SID name is as 8i Lite installation did not ask for any SID name and it just created the polite databse (which works fine from ODBC).
What is the default SID name for 8i Lite ?
How to fix this probelm. Any help is greatly appreciated. VR.

There is some more work you need to do to make JDeveloper work with Oracle Lite. Details are in an earlier response to a similar problem:

Oracle 11g XE connectivity problem

Hello,
I'm trying to setup a Virtual machine for test purposes using VMware Player.
I'm following Oracle® Database Express Edition Installation Guide 11g Release 2 (11.2) for Linux x86-64: http://download.oracle.com/docs/cd/E17781_01/install.112/e18802.pdf
As described there, I've installed Oracle Enterprise Linux 5 Update 2 from DVD V15099-01.zip(Enterprise-R5-U2-Server-x86_64-dvd.iso).
After that followed the instructions in the guide and installed the XE database... so far no errors or problems... while testing from local ssh session :)

I've already disabled my windows firewall for the test - no good. Also SSH works over the network, so I don't think it's a firewall or network issue...maybe I'm missing something in listners configuration or some security setting somewhere?

Hello,
What sort of access? And ssh is working? putty? Using VM NAT, or bridged?
Yes, from my desktop windows to the VM's eth0 interface I could use SSH without any concerns. Yes, I've used PuTTY Client for SSH. For VM is bridged.
That's not relevant to accessing the VM, you'll need to open up ports in the VM host firewall. Port 8080 too if you want to access the Apex pages, along with opening port 1521 for the database listener.
Yes, you are right - had to stop firewall on my VM box... since this is a dummy sandbox I just stopped firewall
service iptables stop
chkconfig iptables off
After that SQL Developer Studio managed to open connection to the XE database on this VM box over the network. Thank you!
You've got all the listener endpoints, including the http 8080 but setting up a server on dhcp isn't optimal unless you have dynamic DNS to register the VM IP for name resolution. Unless a dos box $ ping oracle11xe or $ ping oracle11xe.localdomain from the Win box gets the correct IP address of the VM ...
Sorry I didn't get this one... Could you please give me more information.
I've configured VM(oracle11xe.localdomain) to use static IP address(NO DHCP, I'd like to avoid involving the DHCP Server in my network in this simple test). This leads to me being able to ping it from Win Box only via IP address, what problems may show up from this? My idea was to avoid having problems, if for example I started the VM box in very different environment(lets say another network) and it gets some other IP address, because I didn't knew how oracle XE will feel about the new IP?
Once again - Thank you. Original issue is solved!

Application connection problems between linux & solaris?

HI,
Do you know if I can connect to a server on solaris with a java application and then I compile it on linux why cann't I get to the same application still runing on the solaris machine? A little fuzzy but ... I looked in the /etc/hosts but it looked ok (there were some ip addr there)...
java.net.ConnectException: Connection refused
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:320)
at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:133)
at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:120)
at java.net.Socket.<init>(Socket.java:273)
at java.net.Socket.<init>(Socket.java:100)

Thank you all of you in advance,
I found the problem : it just should have been the correct initialization.

Software Update Error and Application connectivity problems

Hi. Hoping someone can help me with issues I've been having since we added a wireless access point to our network at home two weeks ago. I'm sharing a network with two pcs, a pc laptop and a ps3. All of which are working fine either using the wireless access point or ethernet through our router.
I have a macbook which is picking up the wireless fine, apart from a few applications. The biggest problem is that software update isn't connecting. I get a message telling me there is a networking error: NSURLError Domain - 1100. I go through the network diagnostics and it tells me that my connection is working correctly.
Another (less worrying but annoying) problem is that some widgets (facebook, wikipedia, translater etc) are not picking up the connection either. Facebook iphoto exporter also doesn't work. There is no in-built firewall in the access point and I haven't changed any firewall settings on my system (which was working perfectly with the ethernet connection). All I changed was the DNS server address.
The only time I have used airport previously is in the library at my university, where I needed to use a proxy address. I'm wondering if this may be interfering with my connection settings now, but am unsure of how to change the setting around. I'm a new mac user and this is the first issue I've had issues. Any help/suggestions are thoroughly appreciated.
thanks.

I'd been having this problem for the past few weeks (causing Software Update to fail with NSURLError -100 and the iTunes radio service to fail) and just fixed it myself.
For me the issue had to do with proxy settings in the browser versus proxy settings in System Preferences. For example, if you run Tor/Vidalia with Firefox, the browser has its own proxy settings that get changed when you activate Tor. But if you use Safari or anything else to set up the proxy, it's the network settings under System Preferences that get affected.
To check this, go to (Apple menu)>System Preferences...>Network, then choose whichever network interface you're currently using. If the lock icon in the lower left-hand corner is locked, click on it and authenticate with your password. Now click Configure... and choose the Proxies tab.
On my machine, I have "Configure proxies:" set to "Manually" (I've never used the other option, "Using a PAC file", so if you have that set I'm not sure how to debug it). Now look through the items in the "Select a proxy server to configure" panel. If there is anything checked there, it should be for a specific reason. If something is checked and you don't know why, try unchecking it.
Finally, click on Apply Now (giving your password again if prompted), close the System Preferences dialog, and try Software Update again.
This solved my problems (I had been fiddling with a local proxy for OS X Mail and Thunderbird). Your mileage may vary. Give that a shot and report back if it helps (or if it doesn't).

Oracle 8i Lite connection problem

I'm trying to make connection with Oracle 8i Lite native jdbc driver. I'm getting error "Unable to find driver oracle.lite.poljdbc.POLJDBCDriver" when pressing Test button.
olite40.jar is in IDEClassPath in jdeveloper.ini and Oracle 8i Lite is in Default Project Libraries.
What I've missed?

If you have added the Olite40.jar file to the IDE_CLASSPATH setting in the jdeveloper.ini file, make sure you restarted JDeveloper after editing the ini file.
Also, make sure you specity 'Olite40.jar' not 'olite40.jar' (watch the case of the archive file name).

Oracle database 10g connectivity problem with Report Builder

Hi,
I need to amend a .rdf report and am using the dev10g. I can't connect the test database from report builder.
It is getting the error like :
"ORA-12154 : TNS: could not resolve service name".
I can connect the database from sql*plus, Toad etc. Also It's giving me the response when I run the TNSPING command with the database name.
Could someone advise me that how can I resolve this problem?
Thanks,

set the TNS_ADMIN variable point to the correct tnsnames.ora file
or try the note mentioned in http://www.alexyscorp.com/products.htm
Lastly try opening a command line/dos prompt, set the TNS_ADMIN variablea and start the reports builder from commandline

Problems about deploying Oracle web application (Forms, Reports)

I am going to deploy Oracle web applications (Forms and Reports) and plan to use the same server machine for both Application web server and Database server.
1. How can I enable SSL (for data encryption) on Application web server for Oracle Forms ?
2. Since both Application web server and Database server will use the same machine, do I still need Oracle Advanced Security for data transmission between Application web server and Database server if data encryption for transmission is required ?
3. Can I user Oracle Forms to call Oracle Report on web as I did in Client/Server in the past ?
Experts like you may have come across such problems. Would you please give me some opinions/ideas ?
Regards,
Richard

1. check the paper about the Forms servlet architecture on otn forms section for SSL tips.
3. Check the reports and forms integration paper on otn too.
